Bit 07=0: There are no warnings.
Bit 07=1: A warning has occurred.
Bit 08, Speed reference/speed=reference
Bit 08=0: The motor runs, but the present speed is different from the preset speed reference. It might happen when the speed ramps up/
down during start/stop.
Bit 08=1: The motor speed matches the preset speed reference.
Bit 09, Local operation/bus control
Bit 09=0: [Off/Reset] is activated on the control unit or [2] Local in parameter 3-13 Reference Site is selected. It is not possible to control
the drive via serial communication.
Bit 09=1: It is possible to control the drive via the fieldbus/serial communication.
Bit 10, Out of frequency limit
Bit 10=0: The output frequency has reached the value in parameter 4-12 Motor Speed Low Limit [Hz] or parameter 4-14 Motor Speed
High Limit [Hz].
Bit 10=1: The output frequency is within the defined limits.
Bit 11, No operation/in operation
Bit 11=0: The motor is not running.
Bit 11=1: The drive has a start signal without coast.
Bit 12, Drive OK/stopped, auto start
Bit 12=0: There is no temporary overtemperature on the drive.
Bit 12=1: The drive stops because of overtemperature, but the unit does not trip and resumes operation once the overtemperature
normalizes.
Bit 13, Voltage OK/limit exceeded
Bit 13=0: There are no voltage warnings.
Bit 13=1: The DC voltage in the drive’s DC link is too low or too high.
Bit 14, Torque OK/limit exceeded
Bit 14=0: The motor current is lower than the current limit selected in parameter 4-18 Current Limit.
Bit 14=1: The current limit in parameter 4-18 Current Limit is exceeded.
Bit 15, Timer OK/limit exceeded
Bit 15=0: The timers for motor thermal protection and thermal protection are not exceeded 100%.
Bit 15=1: 1 of the timers exceeds 100%.
9.11.3 Bus Speed Reference Value
Speed reference value is transmitted to the drive in a relative value in %. The value is transmitted in the form of a 16-bit word. The integer
value 16384 (4000 hex) corresponds to 100%. Negative figures are formatted using 2’s complement. The actual output frequency (MAV)
is scaled in the same way as the bus reference.
